技术领域Technical field
本发明属于电子烟技术领域，特别涉及一种电子烟雾化芯、电子烟及其产生烟雾的方法。The invention belongs to the technical field of electronic cigarettes, and particularly relates to an electronic cigarette core, an electronic cigarette and a method for generating smoke.
背景技术Background technique
目前利用发热件加热雾化棉上烟油以产生烟雾供用户吸食的电子烟雾化芯中，发热件与雾化棉直接接触，雾化棉与电子烟油仓内腔相连通。发热件通电后产生的热量直接传递到雾化棉，加热雾化棉上的烟油产生烟雾。Currently, in the electronic cigarette core, which uses a heating element to heat the e-liquid on the atomizing cotton to produce smoke for the user to smoke, the heating element is in direct contact with the atomizing cotton, and the atomizing cotton is connected to the inner cavity of the e-cigarette oil tank. The heat generated after the heating element is energized is directly transferred to the atomizing cotton, heating the e-liquid on the atomizing cotton to produce smoke.
现有的这种通过直接热量传递加热烟油产生烟雾的方法具有以下缺点：The existing method of heating e-liquid to generate smoke through direct heat transfer has the following shortcomings:
第一，由于发热件与雾化棉直接接触，因而雾化棉易被发热件烧焦，影响烟雾口感，影响电子烟使用寿命。First, since the heating element is in direct contact with the atomized cotton, the atomized cotton is easily scorched by the heating element, which affects the taste of the smoke and the service life of the e-cigarette.
第二，在电子烟静置时，发热件长期浸泡在烟油中，发热件表面会凝结有一层烟油渣，当发热件再次工作时会将凝结在其表面的烟油渣烧焦或碳化而产生异味，严重影响烟雾口感并会危及人体健康。Second, when the e-cigarette is left standing and the heating element is soaked in e-liquid for a long time, a layer of e-liquid residue will condense on the surface of the heating element. When the heating element is operated again, the e-liquid residue condensed on its surface will be burned or carbonized. The odor produced will seriously affect the taste of smoke and endanger human health.
第三，为避免雾化棉被发热件局部烧焦，一般将雾化棉设计得较厚，以使其能吸收较多的烟油和热量。同时极有可能雾化棉出现过饱和漏油现象，需要输出功率较大才能雾化成烟雾，因此输出功率越大，电池的使用寿命越短，安全性能越低。Third, in order to prevent the atomized cotton from being partially burned by the heating element, the atomized cotton is generally designed to be thicker so that it can absorb more e-liquid and heat. At the same time, it is very likely that the atomized cotton will be oversaturated and leakage, which requires a larger output power to atomize into smoke. Therefore, the greater the output power, the shorter the battery life and the lower the safety performance.

The heat generated by the heating element is directly transferred to the e-liquid on the atomizing cotton, and the e-liquid is heated to produce smoke. This heating method is easy to burn and produces smoke. The smoke tastes bad and endangers human health. At the same time, the output power of atomization is large, the battery life is short, the e-cigarette life is short, and the safety performance is low. The object of the present invention is to provide an improved electronic cigarette atomizing core, an electronic cigarette and a method for generating smoke in view of the above-mentioned shortcomings of the prior art. The atomized cotton is not easily burned and smoke does not condense on the surface of the heating element. Oil residue, the power of the heating element is small, the smoke tastes good, will not endanger human health, the battery has a long service life, high safety performance, and the e-cigarette has a long service life.
为解决上述技术问题，本发明所采用的技术方案是：In order to solve the above technical problems, the technical solution adopted by the present invention is:
一种电子烟雾化芯，包括用于与电子烟油仓内腔相连通的雾化棉、用于加热雾化棉上烟油以产生烟雾的发热件，其结构特点是所述发热件与雾化棉不直接接触，发热件产生的热量通过热辐射的方式传递至雾化棉。An electronic cigarette atomizing core, including an atomizing cotton used to communicate with the inner cavity of the electronic cigarette oil tank, and a heating element used to heat the cigarette oil on the atomizing cotton to generate smoke. Its structural feature is that the heating element and the atomizer are The chemical cotton is not in direct contact, and the heat generated by the heating element is transferred to the atomized cotton through thermal radiation.
借由上述结构，发热件与雾化棉不直接接触。当发热件工作时，通过热辐射的方式将锁存在雾化棉上的烟油加热雾化成烟雾供用户吸食。由于发热件与雾化棉不接触，所以雾化棉不容易被发热件产生的热量烧焦；由于发热件与雾化棉不接触，发热件不与烟油接触或者发热件表面没有烟油粘结，所以发热件表面不会凝结有烟油渣，所以在发热件工作过程中不会出现碳化发热件表面的烟油而使烟雾有异味的现象，所以烟雾口感更好，不会危及人体健康，电子烟使用寿命长。With the above structure, the heating element and the atomizing cotton are not in direct contact. When the heating element is working, the e-liquid locked on the atomizing cotton is heated and atomized into smoke through thermal radiation for the user to smoke. Since the heating element is not in contact with the atomized cotton, the atomized cotton is not easily scorched by the heat generated by the heating element; because the heating element is not in contact with the atomizing cotton, the heating element is not in contact with the e-liquid or there is no e-liquid sticking to the surface of the heating element. Therefore, there will be no cigarette oil residue condensed on the surface of the heating element, so during the working process of the heating element, the cigarette oil on the surface of the heating element will not be carbonized and the smoke will have a peculiar smell, so the smoke will taste better and will not endanger human health. , e-cigarettes have a long service life.
作为一种优选方式，所述发热件套设于雾化棉内，发热件侧壁与雾化棉侧壁之间具有热辐射间隙。As a preferred way, the heating element is set inside the atomized cotton, and there is a heat radiation gap between the side wall of the heating element and the side wall of the atomizing cotton.
借由上述结构，由于雾化棉包覆在发热件的外表面，所以当发热件工作时，发热件所产生的热量全部被充分利用于有助于烟油被雾化产生烟雾，以使烟油被雾化生产烟雾的更速度；在这雾化过程中大部分热量通过热辐射间隙以热辐射的方式将锁存在雾化棉上的烟油加热雾化成烟雾，避免有雾化棉被烧焦和烟油被碳化的现象，提升烟雾口感。With the above structure, since the atomizing cotton is covered on the outer surface of the heating element, when the heating element is working, all the heat generated by the heating element is fully utilized to help the e-liquid be atomized to generate smoke, so that the smoke can be evaporated. The faster the oil is atomized to produce smoke; during this atomization process, most of the heat passes through the thermal radiation gap to heat and atomize the e-liquid locked on the atomized cotton into smoke to avoid burning the atomized cotton. The phenomenon of carbonization of coke and e-liquid improves the taste of smoke.
作为一种优选方式，还包括雾化套，发热件及雾化棉均位于雾化套内，雾化套上开设用于连通油仓内腔及雾化棉的第一过油孔。As a preferred way, it also includes an atomization sleeve, the heating element and the atomization cotton are located in the atomization sleeve, and the atomization sleeve is provided with a first oil hole for connecting the inner cavity of the oil tank and the atomization cotton.
进一步地，所述雾化套内还设有隔热管，隔热管套设于雾化棉外，隔热管上开设连通第一过油孔与雾化棉的第二过油孔。Furthermore, the atomization sleeve is also provided with a heat-insulating tube. The heat-insulating tube is set outside the atomizing cotton. The heat-insulating tube is provided with a second oil-passing hole that connects the first oil-passing hole and the atomizing cotton.
进一步地，雾化棉与发热件之间设有固定架，固定架的张力使雾化棉的侧壁与隔热管的内侧壁相抵接。Further, a fixed frame is provided between the atomized cotton and the heating element, and the tension of the fixed frame causes the side wall of the atomized cotton to contact the inner wall of the heat insulating tube.
借由上述结构，通过固定架将雾化棉固定在雾化套内，以使雾化棉的一侧贴紧第二过油孔，烟油供给更通畅；以使雾化棉的另一侧不会因雾化棉的毛絮而与发热件接触，避免被烧焦，以及避免堵塞气流经过热辐射间隙的现象。With the above structure, the atomizing cotton is fixed in the atomizing sleeve through the fixing frame, so that one side of the atomizing cotton is close to the second oil hole, and the e-liquid supply is smoother; so that the other side of the atomizing cotton is The lint of the atomized cotton will not come into contact with the heating element to avoid being burned and blocking the air flow through the heat radiation gap.
进一步地，进气通道设于发热件的中心轴处，雾化套内设有与进气通道出口相接并垂直的气流反射腔；气流反射腔连通进气通道与热辐射间隙。Further, the air inlet channel is located at the central axis of the heating element, and an air flow reflection cavity connected and vertical to the outlet of the air inlet channel is provided in the atomization sleeve; the air flow reflection cavity connects the air inlet channel and the heat radiation gap.
借由上述结构，将进气通道设置在发热件的中间。当吸烟时气流从进气通道进入雾化套内，然后进气通道出口处的气流反射腔将空气反射打散，从而使气流能够均匀地分散到热辐射间隙，然后气流从热辐射间隙流出且将热辐射间隙内已经被加热雾化后产生的烟雾充分带出，最后被用户吸食。With the above structure, the air inlet channel is arranged in the middle of the heating element. When smoking, the airflow enters the atomization sleeve from the air inlet channel, and then the airflow reflection cavity at the outlet of the air inlet channel disperses the air reflection, so that the airflow can be evenly dispersed into the heat radiation gap, and then the airflow flows out from the heat radiation gap and The smoke generated after being heated and atomized in the heat radiation gap is fully brought out, and finally smoked by the user.
进一步地，所述隔热管与雾化套之间设有隔热腔。Further, a heat insulation cavity is provided between the heat insulation tube and the atomization sleeve.
借由上述结构，隔热管既可以固定雾化棉又可以隔绝雾化棉上的热量传递到电子烟外表面。由于在隔热管和雾化套之间设置有隔热腔，双重隔热，可防止电子烟外表面温度过高，同时也可以防止发热件工作过程中产生的热量流失，起到保温效果，提高热量的利用率。With the above structure, the heat insulation tube can not only fix the atomizing cotton but also isolate the heat on the atomizing cotton from being transferred to the outer surface of the electronic cigarette. Since there is a heat insulation cavity between the heat insulation tube and the atomizer sleeve, double heat insulation can prevent the outer surface temperature of the e-cigarette from being too high. It can also prevent the heat loss generated during the operation of the heating element, thus achieving a heat preservation effect. Improve heat utilization.
作为另一种优选方式，还包括雾化套，雾化棉通过雾化套上的凸部固定在雾化套内，发热件套设于该凸部外。As another preferred method, it also includes an atomizing sleeve, the atomizing cotton is fixed in the atomizing sleeve through a convex part on the atomizing sleeve, and the heating element is set outside the convex part.
进一步地，所述雾化套外设有隔热管，隔热管与雾化套之间设有隔热腔。Further, a heat-insulating pipe is provided outside the atomizing sleeve, and a heat-insulating cavity is provided between the heat-insulating pipe and the atomizing sleeve.
进一步地，所述隔热管上开设与热辐射间隙相通的进气斜孔，所述雾化套上开设与热辐射间隙相通的出气斜孔；气流从进气斜孔进入后，在热辐射间隙内呈螺旋流动，经出气斜孔流出。Further, the insulating tube is provided with an air inlet inclined hole connected with the heat radiation gap, and the atomization sleeve is provided with an air outlet inclined hole connected with the heat radiation gap; after the airflow enters from the air inlet inclined hole, the heat radiation There is a spiral flow in the gap and flows out through the inclined air outlet hole.
借由上述结构，当外界空气进入热辐射间隙内时，通过隔热管上的进气斜孔进入热辐射间隙，空气在热辐射间隙内形成螺旋气流，最后从出气斜孔排出，进而将烟雾带入用户口腔中。进气斜孔和出气斜孔均沿进气通道内壁切线方向设置，以确保热辐射间隙内的气流形成螺旋气流，在此过程中，由于螺旋气流的离心作用可以将烟雾进行筛选，从而使被带出的烟雾口感更加细腻。雾化套上的凸部既可以固定雾化棉又可以改变热辐射间隙的大小，以确保气流贴近雾化棉流动即气流更好的通过热辐射间隙，然后烟雾被带出更充分，烟雾口感好，使用户吸烟过程中的满足感更强。With the above structure, when outside air enters the heat radiation gap, it enters the heat radiation gap through the air inlet inclined hole on the heat insulating pipe. The air forms a spiral airflow in the heat radiation gap, and is finally discharged from the air outlet inclined hole, thereby removing the smoke. into the user's mouth. The air inlet inclined holes and the air outlet inclined holes are arranged along the tangential direction of the inner wall of the air inlet channel to ensure that the air flow in the heat radiation gap forms a spiral air flow. During this process, the centrifugal effect of the spiral air flow can screen the smoke, thereby making the smoke The taste of the smoke brought out is more delicate. The convex part on the atomization sleeve can both fix the atomization cotton and change the size of the heat radiation gap to ensure that the airflow is close to the atomization cotton, that is, the airflow can better pass through the heat radiation gap, and then the smoke is brought out more fully, and the smoke tastes better. Good, making users feel more satisfied during smoking.
作为一种优选方式，所述热辐射间隙为0.6～5mm，优选为1.2～3.5mm。As a preferred way, the heat radiation gap is 0.6 to 5 mm, preferably 1.2 to 3.5 mm.
热辐射间隙越小，发热件的辐射热就越容易被雾化棉吸收雾化，能量损耗就越低，因此所需的雾化功率越小，因此热辐射间隙优选为0.6～5.0mm，更优选为1.2～3.5mm，有效的解决了在确保烟雾量能够满足用户需求的情况下，不会出现烧棉的现象，且需要的雾化功率低，又可以延长电池的使用寿命。The smaller the thermal radiation gap, the easier it is for the radiant heat of the heating element to be absorbed and atomized by the atomized cotton, and the lower the energy loss, so the smaller the required atomization power. Therefore, the thermal radiation gap is preferably 0.6 to 5.0mm, more It is preferably 1.2~3.5mm, which effectively solves the problem of ensuring that the amount of smoke can meet the user's needs without burning cotton, and the required atomization power is low, and the service life of the battery can be extended.
作为一种优选方式，所述雾化棉的厚度为0.5～3mm，优选为0.8～2.1mm。As a preferred way, the thickness of the atomized cotton is 0.5-3mm, preferably 0.8-2.1mm.
雾化棉的厚度越厚存储的烟油越多，也就是说需要更多的功率去将这些烟油雾化成烟雾，因此其厚度优选为0.5～3.0mm，更优选为0.8～2.1mm。当雾化棉的厚度为0.5-3.0mm时，需要雾化功率P＝6-18W才能使烟油雾化成烟雾；优选的，当雾化棉的厚度为0.8～2.1mm时，需要雾化功率8～15W就可以雾化产生烟雾，功率越低，电池的安全性能越好，寿命越长。The thicker the atomization cotton, the more e-liquid it can store, which means more power is needed to atomize the e-liquid into smoke. Therefore, its thickness is preferably 0.5 to 3.0 mm, and more preferably 0.8 to 2.1 mm. When the thickness of the atomized cotton is 0.5-3.0mm, the atomizing power P = 6-18W is required to atomize the e-liquid into smoke; preferably, when the thickness of the atomized cotton is 0.8-2.1mm, the atomizing power is required 8~15W can atomize and produce smoke. The lower the power, the better the safety performance of the battery and the longer its life.
当发热件工作时，雾化棉所吸收到的热辐射能量中有小部分能量被烟油吸收预热，而大部分能量用于雾化烟油和散发在空气和烟雾中，由于雾化棉的厚度比较薄，存储的烟油有限，所以当发热件工作时，可在0.1秒～2秒时间内使烟油雾化形成烟雾，即出烟速度快，能量利用率高，从而降低功率，延长电池的使用时间。When the heating element is working, a small part of the thermal radiation energy absorbed by the atomizing cotton is absorbed by the e-liquid for preheating, while most of the energy is used to atomize the e-liquid and be distributed in the air and smoke. Due to the atomizing cotton, The thickness is relatively thin and the stored e-liquid is limited. Therefore, when the heating element is working, the e-liquid can be atomized to form smoke in 0.1 to 2 seconds, that is, the smoke is emitted quickly and the energy utilization rate is high, thus reducing the power. Extend battery life.

The heating element is not in direct contact with the atomizing cotton. The heat generated is transferred to the atomizing cotton through thermal radiation.
作为一种优选方式，发热件套设于雾化棉内，气流从发热件中心孔一端进入，经发热件中心孔另一端的气流反射腔反射入发热件与雾化棉之间的热辐射间隙并流出。As a preferred way, the heating element is set inside the atomized cotton.

如图1所示，雾化芯20包括用于与电子烟油仓1内腔相连通的雾化棉2、用于加热雾化棉2上烟油以产生烟雾的发热件3，所述发热件3与雾化棉2不直接接触，发热件3产生的热量主要通过热辐射的方式传递至雾化棉2用于加热雾化烟油。As shown in Figure 1, the atomizing core 20 includes an atomizing cotton 2 used to communicate with the inner cavity of the electronic cigarette oil tank 1, and a heating element 3 used to heat the e-liquid on the atomizing cotton 2 to generate smoke. The component 3 is not in direct contact with the atomizing cotton 2. The heat generated by the heating component 3 is mainly transferred to the atomizing cotton 2 through thermal radiation for heating the atomized e-liquid.
所述发热件3套设于雾化棉2内，发热件3侧壁与雾化棉2侧壁之间具有热辐射间隙4，也可以这样理解：发热件3外表面包围有雾化棉2，但是发热件3与雾化棉2又不接触，所以发热件3表面也没有粘结烟油；所以当发热件3工作时，发热件3所产生的热量通过热辐射的方式加热雾化雾化棉2上的烟油所产生的烟雾口感更纯，没有异味。The heating element 3 is set inside the atomized cotton 2. There is a heat radiation gap 4 between the side walls of the heating element 3 and the atomized cotton 2. It can also be understood as follows: the outer surface of the heating element 3 is surrounded by the atomized cotton 2. , but the heating element 3 is not in contact with the atomizing cotton 2, so there is no smoke oil adhered to the surface of the heating element 3; therefore, when the heating element 3 works, the heat generated by the heating element 3 heats the atomization mist through thermal radiation. The smoke produced by the e-liquid on chemical cotton 2 has a purer taste and no peculiar smell.
由于热辐射的能量随辐射热源的距离增大而减小，所以本实施列中所述热辐射间隙4的大小b为0.6～5mm，优选为1.2～3.5mm。Since the energy of thermal radiation decreases as the distance from the radiation heat source increases, the size b of the thermal radiation gap 4 in this embodiment is 0.6 to 5 mm, preferably 1.2 to 3.5 mm.
为了确保发热件3与雾化棉2不接触且在0.1秒～2秒时间内使烟油雾化形成烟雾，所以本实施列中所述雾化棉2的厚度a为0.5～3mm，优选为0.8～2.1mm。In order to ensure that the heating element 3 does not contact the atomized cotton 2 and that the e-liquid is atomized to form smoke within 0.1 to 2 seconds, the thickness a of the atomized cotton 2 in this embodiment is 0.5 to 3 mm, preferably 0.8～2.1mm.

雾化套5底部与连接件15相连。连接件15上设有固定座16，连接件15通过雾化套5底部的凸缘(未编号)与固定座16固定连接，发热件3上通过焊接等方式连接有两条引线17，这两条引线17作为发热件3的两电极线；引线17的强度至少可以支撑起发热件3使发热件3即不与雾化棉2接触也不与进气管14接触，比如引线17用钢琴线、不锈钢丝等制作而成；发热件3的引线17、进气管14均通过固定座16固定，所以发热件3通过引线17悬空固定在雾化棉2与进气管14之间，以使发热件3即不与雾化棉2接触也不与进气管14接触，减少进气管14导走一部分热量而影响雾化效果。The bottom of the atomizer sleeve 5 is connected to the connecting piece 15 . The connecting piece 15 is provided with a fixed base 16. The connecting piece 15 is fixedly connected to the fixed base 16 through the flange (unnumbered) at the bottom of the atomizer sleeve 5.

The component 3 is not in direct contact with the atomizing cotton 2. The heat generated by the heating component 3 is transferred to the atomizing cotton 2 through thermal radiation for heating the atomized e-liquid.
所述发热件3套设于雾化棉2内，发热件3侧壁与雾化棉2侧壁之间具有热辐射间隙4，也可以这样理解：发热件3外包围有雾化棉2，但是发热件3与雾化棉2又不接触，所以发热件3表面没有粘结有烟油；所以当发热件3工作时，发热件3所产生的热量通过热辐射的方式加热雾化雾化棉2上的烟油所产生的烟雾口感更纯，没有异味。The heating element 3 is set inside the atomized cotton 2. There is a heat radiation gap 4 between the side walls of the heating element 3 and the atomized cotton 2. It can also be understood as follows: the heating element 3 is surrounded by the atomized cotton 2. However, the heating element 3 is not in contact with the atomizing cotton 2, so there is no smoke oil adhered to the surface of the heating element 3; therefore, when the heating element 3 works, the heat generated by the heating element 3 heats and atomizes the atomization through thermal radiation. The smoke produced by the e-liquid on Cotton 2 has a purer taste and no peculiar smell.
由于热辐射的能量随辐射热源的距离增大而减小，所以本实施列中所述热辐射间隙4的大小b为0.6～5mm，优选为1.2～3.5mm。Since the energy of thermal radiation decreases as the distance from the radiation heat source increases, the size b of the thermal radiation gap 4 in this embodiment is 0.6 to 5 mm, preferably 1.2 to 3.5 mm.

雾化棉2与发热件3之间设有固定架7，固定架7的张力使雾化棉2的侧壁与雾化套5的内侧壁相抵接。A fixing frame 7 is provided between the atomizing cotton 2 and the heating element 3. The tension of the fixing frame 7 causes the side wall of the atomizing cotton 2 to abut against the inner wall of the atomizing sleeve 5.
隔热管6底部与连接件15相连。连接件15上设有固定座16，固定座16卡设在隔热管6底部，发热件3上通过焊接等方式连接有两条引线17，这两条引线17作为发热件3的两电极线；引线17的强度至少可以支撑起发热件3使发热件3即不与雾化棉2接触也不与凸部502接触，比如引线17用钢琴线、不锈钢丝等制作而成。发热件3的引线17通过固定座16固定，所以发热件3通过引线17悬空固定在雾化棉2和凸部502之间，以使发热件3即不与雾化棉2接触也不与凸部502接触，防止凸部502带走一部分热量而影响雾化效果。The bottom of the heat insulating pipe 6 is connected to the connecting piece 15 . The connector 15 is provided with a fixed seat 16, which is clamped at the bottom of the heat insulating tube 6. The heating element 3 is connected to two leads 17 by welding or other methods. These two leads 17 serve as the two electrode lines of the heating element 3. ; The strength of the lead wire 17 can at least support the heating element 3 so that the heating element 3 neither contacts the atomized cotton 2 nor the convex portion 502. For example, the lead wire 17 is made of piano wire, stainless steel wire, etc. The lead 17 of the heating element 3 is fixed through the fixing base 16, so the heating element 3 is suspended between the atomizing cotton 2 and the protrusion 502 through the lead 17, so that the heating element 3 neither contacts the atomizing cotton 2 nor the protrusion. The protruding portion 502 is in contact with the protruding portion 502 to prevent the protruding portion 502 from taking away part of the heat and affecting the atomization effect.
雾化芯20还包括内电极18，内电极18与连接件15之间通过绝缘环19绝缘相连。The atomizing core 20 also includes an internal electrode 18 , and the internal electrode 18 is insulated from the connector 15 through an insulating ring 19 .
